It's Polish Independence Day, and like in any other country, the youngins love celebrating liberty by destroying things. German (?) and Polish "youths" butted heads with (and threw things at) riot cops in Warsaw. Check out the view from above.

Although the whine of the drone is irritating, it sure beats having your skull cracked open by a cop. This is actually a pretty terrific news-gathering tool—can you imagine a tiny, nigh-impossible to destroy camera drone over a battlefield? [YouTube via Reddit, thanks Adrian!]
